[0028] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

Therefore, they should not be construed as limitations on this patent.

[0030] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0031] Reference Figures 1 to 4 A stainless steel air cylinder for high-speed rail includes: a cylinder body 1, which is the main body of the air cylinder and is made of stainless steel. Stainless steel has excellent corrosion resistance and strength, making it suitable for use in high-pressure, high-speed high-speed rail environments; and an end cap 4, which is located at one end of the cylinder body 1. The surface of the end cap 4 is connected to an end cap 3 by threads 8 to seal the cylinder body 1 and prevent gas leakage. The design of the end cap 4 facilitates the installation and removal of the end cap 3, while ensuring a tight connection between the end cap 3 and the cylinder body 1. The connection between the end cap 3 and the end cap 4 is achieved by threads. This connection method is simple and reliable, ensuring that the gas inside the cylinder body 1 will not leak. The guide section 5, which is constructed inside the cylinder body 1, is spirally arranged to improve the flow state of gas in the cylinder body. It can guide the airflow to a certain extent, so that part of the airflow can be guided and adhered to the inner wall of the air cylinder. Under the action of the generated spiral airflow, it can drive the movement of impurities on the inner wall of the air cylinder, reducing the impact of corrosion, etc. A reinforcing component is connected between the end cap 3 and the end head 4 to enhance the connection strength between the end cap 3 and the cylinder body 1, and to prevent the end cap 3 from loosening or being damaged due to pressure generated by high-pressure gas or vibration. A sealing gasket 6 is connected inside the end cap 3 to further improve the sealing performance of the cylinder body.

[0032] Specifically, refer to Figures 1 to 4 The reinforcing components include: an elastic element 12, a mating portion 11, a limiting groove 10, a stabilizing element 7, and an insertion hole 9. The limiting groove 10 is constructed on the surface of the end 4. The mating portion 11 is fixed to one end of the end cap 3 and corresponds to the limiting groove 10. The stabilizing element 7 is connected to the surface of the end 4 through the elastic element 12. The insertion hole 9 is opened through the surface of the mating portion 11. In this embodiment, the stabilizing element 7 is first pulled out and the elastic element 12 is stretched. The mating portion 11 at one end of the end cap 3 can be connected to the limiting groove 10, so that the stabilizing element 7 can be aligned with the insertion hole 9 to be released. At this time, the elastic element 12 restores its elasticity to pull the stabilizing element 7 back to its original position and insert it into the insertion hole 9, which can further fix the end cap 3.

[0033] Furthermore, the limiting groove 10 is arranged in a ring shape and is located outside the thread 8. This design facilitates the mating part 11 to cooperate with the limiting groove 10, thereby enabling the end cap 3 to be better connected to the end head 4 and providing installation space for the connection of subsequent reinforcement components.

[0034] Furthermore, one end of the stabilizing member 7 is located inside the elastic member 12, and one end of the stabilizing member 7 is provided through the end head 4. Through this design, a more robust fixed structure can be formed, preventing the stabilizing member 7 from shaking due to the action of the elastic member 12. Moreover, the elastic action generated by the elastic member 12 can facilitate the reset and other activities of the stabilizing member 7, improving flexibility.

[0035] Furthermore, the retaining member 7 corresponds to the insertion hole 9. With this design, the retaining member 7 can be inserted into the insertion hole 9 after being reset, further fixing the end cap 3, so as to reduce the impact of bumps and vibrations on the end cap 3 when sealing the end 4 and causing it to loosen.

[0036] Furthermore, the sealing gasket 6 abuts against the end 4, and the sealing gasket 6 is made of elastic material. This design can fill the tiny gap between the end cap 3 and the cylinder 1, effectively preventing the medium (such as gas or liquid) from leaking from the connection and improving the sealing performance.

[0037] Furthermore, a support part 2 for fixing and supporting the cylinder body 1 is installed at the lower part of the cylinder body 1. This design provides a stable support, ensures that the cylinder body 1 can remain stable during operation, and prevents the cylinder body 1 from falling off or tipping over in case of accidents (such as strong vibration, collision, etc.).

[0038] Working principle: When using this utility model, when the air cylinder is first closed, the end cap 3 and the end head 4 can be threaded together. The disassembly and assembly are convenient, and the threaded connection has good strength and sealing performance. In addition, the reinforcement component provided when connecting the end cap 3 and the end head 4 can further limit the distance between the end cap 3 and the end head 4, reducing the movement of the end cap 3. At this time, the operator first pulls out the stabilizing member 7 and stretches the elastic member 12. The mating part 11 at one end of the end cap 3 can be connected to the limiting groove 10, so that the stabilizing member 7 can be aligned with the insertion hole 9 to be loosened. At this time, the elastic member 12 restores its elasticity to pull the stabilizing member. The component 7 is reset and inserted into the insertion hole 9, which can further fix the end cap 3, so as to reduce the impact of the end cap 3 on the vibration when sealing the end 4 and loosen it, improve the connection strength and sealing of the air cylinder. The sealing gasket 6 inside the end cap 3 can improve the sealing performance, while the guide part 5 inside the cylinder body 1 is constructed in a spiral shape, so that when the airflow passes through the air cylinder, the spirally arranged guide part 5 can have a certain guiding effect on the airflow, so that part of the airflow can be guided and adhered to the inner wall of the air cylinder, so that the impurities on the inner wall of the air cylinder can be moved under the action of the generated spiral airflow, reducing the impact of corrosion.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
